 * <!-- begin-model-doc -->
 * The abstract supertype for temporal geometric primitives.
 *        A temporal geometry must be associated with a temporal reference system via URI. 
 *        The Gregorian calendar with UTC is the default reference system, following ISO 
 *        8601. Other reference systems in common use include the GPS calendar and the 
 *        Julian calendar.
